Stored as network of points joined to make a sequence of adjacent triangles
Simple algorithm defining how to store these
- No edge is described twice
- No location is connected to more than three other locations
- No location is connected to a location with a lower number
- When a location is connected to three locations, two triangles formed: <Location First Second> and <Location First Third>
